Question 1


To teach an Intermediate Phase learner how to calculate fractions, I will first explain the
basic concepts of fractions and how to add, subtract, and simplify fractions. Then, I will
refer to the given expressions and guide the learner through the calculations.

1.1.1. 4 + 3 + 3/5

To calculate the expression, we start by adding the whole numbers:
4+3=7

Then, we add the fractions:
7 + 3/5

To add fractions, we need a common denominator. In this case, the denominators are 1
and 5. The least common multiple of 1 and 5 is 5.

Now, we can rewrite the fractions with a common denominator:
3/5 = (3/5) * (1/1) = (3/5) * (5/5) = 15/25

Adding the fractions:
7 + 15/25

, To add mixed numbers with fractions, we need to convert the mixed number to an
improper fraction. In this case, 7 can be written as 7/1.

Adding the fractions:
7/1 + 15/25

To add fractions, we need a common denominator. In this case, the denominators are 1
and 25. The least common multiple of 1 and 25 is 25.

Now, we can rewrite the fractions with a common denominator:
7/1 = (7/1) * (25/25) = 175/25
15/25 = 15/25

Adding the fractions:
175/25 + 15/25 = (175 + 15)/25 = 190/25

Finally, we simplify the fraction, if possible:
190/25 = 38/5

Therefore, the answer to 1.1.1 is 38/5.

1.1.2. 2 - 1 + 1

To calculate the expression, we start by subtracting the numbers from left to right:
2-1=1

Then, we add the remaining number:
1+1=2

Therefore, the answer to 1.1.2 is 2.

1.1.3. 4/2 + 2 + 1/5

To calculate the expression, we start by adding the fractions:
4/2 + 1/5

To add fractions, we need a common denominator. In this case, the denominators are 2
and 5. The least common multiple of 2 and 5 is 10.

Now, we can rewrite the fractions with a common denominator:
4/2 = (4/2) * (5/5) = 20/10
1/5 = 1/5
